1 - 1/89 as a fraction

Learn how to find what is 1 minus 1/89 in fraction form just in a few minutes. We have covered the easiest method to write 1 - 1/89 as a fraction and decimal.

Summary: 1 minus 1/89 = 88/89
Since both fractions have unequal denominators, 1 minus 1/89 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1 and fraction 1/89 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 89. 89 is the LCM of 1 and 89. Multiplying the LCM 89 with the numerators and denominators of both fractions (1 x 89/89) - (1/89 x 89/89), and simplify further in order to have the common denominator. So the equivalent fraction for 1 is 89/89 and for 1/89 is 1/89. By simplifying this fraction subtraction 89/89 - 1/89, it becomes 88/89.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/89 from 1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1 minus 1/89.
1. LCM method
2. Cross multiplication method.

(1) - (1/89) using LCM Method:
What is 1 minus 1/89 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/89

What to be found?
(1) - (1/89) = ?
Find what's the difference between 1 and 1/89.

step 2 Compare the denominators of fractions 1 and 1/89 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1 and 1/89 are not equal, it is said to be unlike fractions subtraction.

step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 1 and 1/89:
The LCM of 1 and 89 is 89.

step 4 Write the fractions 1 and 1/89 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1 - 1/89
= [(1 x 89)/(1 x 89)] - [(1 x 89)/(89 x 89)]

step 5 Simplify the expression to have common denominator:
= 89/89 - 1/89

step 6 Take the common values out and rewrite the above expression like the below:
= 1/89 x (89/1 - 1/1)
= 1/89 x (89 - 1)

step 7Simplify the above expression further:
= 1/89 x 88
= 88/89
1 - 1/89 = 88/89

Hence,
1 minus 1/89 as a fraction is 88/89.

1 - 1/89 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/89

What to be found?
(1)-(1/89) = ?
Find what's the difference between 1 and 1/89.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 89), find the product of numerator of Fraction B and denominator of Fraction A (1 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 89) and rewrite the equation as like the below:
= (1 x 89) - (1 x 1)/(1 x 89)

step 3 Simplify and rewrite the fraction:
= (89 - 1)/89
1 - 1/89 = 88/89

Hence,
1 minus 1/89 in fraction is 88/89
